长期以来，鹦鹉螺属的起源和进化一直被糟糕的化石记录、明显的形态保守主义和关于现存物种分类的混乱所掩盖。对蛋白质多态的研究有望解决这一僵局，因为这种变异反映了基因本身的结构，应该比表型特征更清楚地记录动物的分子系统发育。本章报道的鹦鹉螺属分子进化的初步研究以一种有用的预测方式阐明了其中一些长期存在的问题，并表明这些问题并不是现有技术无法完全解决的。
The origin and evolution of the genusNautilushave long been obscured by the poor fossil record, by apparent morphological conservatism, and by confusion regarding the taxonomy of the living species. Studies of protein polymorphisms promise a solution to this impasse, since such variation reflects the structure of the genes themselves and should record the molecular phylogeny of the animals more clearly than do phenotypic characters. The preliminary study of the molecular evolution ofNautilusreported in this chapter elucidates some of these long-standing problems in a usefully predictive manner and suggests that they are not beyond full resolution with existing techniques.
